Object A is producing a sound whose intensity measures 25 dB at a distance of 1 meter. This sound is, roughly speaking, a band-limited sawtooth wave with a fundamental frequency of about 35 Hz.
Object B is being driven up and down a distance of about 0.5 mm with an acceleration of 0.3 times that of gravity. The sound doing this is a sine wave with a frequency of 35 Hz.
I'd like to compare the peak accelerations experienced by the two objects.
